--- Comment #1 from Uros Bizjak <ubizjak at gmail dot com> 2010-12-25 19:33:53 UTC --- The testcase is useless, it only shows that the call to pow() returns wrong result. In case this is really a gcc bug, please provide runtime testcase from the implementation of pow and also exact compile flags that can be used to trigger the bug.
